Thousands of migrating birds have been dying before reaching England this week because of an appalling combination of fog and winds around the coast, according to the Royal Society for the Protection of Birds (RSPB).
Some fishermen have told the charity of the deaths of many exhausted and disorientated "garden" birds plunging into the sea around their vessels, a spokesman said.
England's east coast, from Northumberland to Kent, has seen the arrival of many birds, including redwings, fieldfares, bramblings and blackbirds, perhaps numbering in their millions.
Hundreds of birds of prey have been poisoned because the Government has failed to fully implement laws designed to protect them, MPs warned.
Rules brought in six years ago made it an offence to possess poisons used to kill birds of prey, but an order listing which poisons it was illegal to have was not introduced, the Environmental Audit Committee said.
A report by the committee found wildlife protection laws are in a mess. In some cases efforts to tackle crimes are being hampered by rules that are "almost Pythonesque in their absurdity".
